ESCAPEMENT.

SPECIFICATION forming part of Letters Patent No. 302,851, dated July 29, 1884.

Application filed May 31, 1883.

T0 {ZZZ whom it may concern.-

Be it known that 1, AUGUST W. KIENIOFF, a citizen of the United States, residing at Dallas, in the county of Polk and State of Oregon. have invented a new and useful Improvement in Time-Piece Escapements, of which the/following is a full, clear, and exact description, reference being had to the accompanying drawings and letters of reference marked thereon, in which Figure 1 is an end View of my improved escapement. Fig. 2 is a sectional view on line or as, Fig. 1; and Fig. 3 is a sectional view on line y y, Fig. 1.

Similar letters indicate like parts in all the figures.

My invention relates to balance-wheel or pendulum escapements in time-pieces; and it consists in the peculiar construction and arrangement of the parts, as hereinafter more fully set forth, and pointed out in the claims.

Referring to the drawings, in which I have shown the device applied to a balance-wheel escapement for a time-piece, (t represents the balance-staff of a time-piece operated by .a hairspring, b, and carrying the balance-wheel c, and a pallet or roller, d, which engages with the escapement-wheel h, operated by a weight or spring through a train of wheels.

-Z represents a pawl hinged at one end to the frame of the time-piece, and provided at its opposite end with a hook, Z, adapted to engage with a tooth of the escapement-wheel h and prevent it from revolving.

m represents a spring pressing on the back face of the pawl Z, and forcing its hooked end Z into engagement with a tooth of the escapement-wheel h.

n represents an arm secured at one end to the spring-pawl Z at 0, and resting near its (No model.)

opposite end on the block secured to the frame of the time-piece.

1) represents a keeper secured to the block 0, through which the arm it passes, the keeper serving as a guide to the arm n in its reeiprocations. The arm it extends upwardly sufficiently far to allow its end to be struck by the pallet or roller d in its oscillations. In practice the pallet or roller (1, operated by the hairspring, will strike the upper end of the arm n of the spring-pawl Z, throwing its hooked tooth Z out of engagement with a tooth of the escapementwheehwhich imparts an impulse to the balance-wheel, and allows the escapement to revolve one tooth, when the spring at will force the spring-pawl Z into engagement with the next tooth of the escapement-wheel,which process will continue for the other teeth of the escapement-wheel.

My escapement can be applied to a common toothed escapement-wheel.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, with the balance-staff a and pallet or roller 61 secured thereto. of the escapement-wheel h and spring-pawl Z, having arm a, substantially as shown and de scribed.

2. The combination, with the balance-staff ct, balance-wheel 0, spring I), and pallet or roller d, of the escapement-wheel h, lever Z, having hook Z, arm n, and block 12, having keeper 1), substantially as shown and described.
